A method for preserving autonomous operation of a transport climate control system is provided. The method includes the controller determining whether a regulatory compliance at a current location is restricting and/or preventing the use of a prime mover for powering the transport climate control system while a transport unit is in transit. When the controller determines that use of the prime mover is not being restricted or prevented because of a regulatory compliance, the method includes operating the transport climate control system and the transport power system in an energy harvesting operation mode for storing excess power generated by the prime mover into the auxiliary energy storage. When the controller determines that use of the prime mover is being restricted or prevented because of a regulatory compliance, the method includes the controller instructing the auxiliary energy storage to provide power to the transport climate control system.

A transport climate control system is described which comprises a controller configured to determine a power demand of a climate control circuit of the system and to provide power to the climate control circuit in a first power mode when the power demand is above a power threshold and to provide power to the climate control circuit in a second power mode when the power demand is at or below the power threshold. In the first power mode, power is provided from a prime mover and, in the second power mode, power is provided from an energy storage source and not the prime mover. Corresponding methods for controlling a transport climate control system are also described.

The power management system (200; 300; 400) is configured to supply electrical power to the transport refrigeration unit (150) from the battery unit (240; 340; 440) responsive to a power demand of the transport refrigeration unit (150).

Disclosed is a transport refrigeration system including: an engine that is dedicated to the transport refrigeration system; a primary battery that is dedicated to the transport refrigeration system, the primary battery being electrically connected to the engine; and a jumper battery electrically connected to the primary battery, the jumper battery configured to automatically boost the primary battery when the primary battery fails to start the engine.

A system for PTO-driven refrigeration includes a generator that is configured to be mechanically connected to a power takeoff (PTO) and a converter that is configured to receive AC power from the generator and is operable to convert the AC power to DC power. The generator is connected to a charge controller that is connected to an energy storage element. The energy storage element is connected to a controller configured to receive DC power and provide AC power to a motor. The motor may be mechanically connectable to a refrigeration system. The energy storage element is further configured to receive power from a second charge controller that receives power via an AC power input or solar system.

A transport refrigeration system includes a transport refrigeration unit having a refrigerant circuit through which a refrigerant is circulated in heat exchange relationship with air drawn from a cargo box, a fuel-fired engine for powering the refrigeration unit and having an exhaust system through which exhaust gases generated by the engine are discharged and an engine coolant circuit, an engine exhaust gases to engine coolant heat exchanger, and an engine coolant circuit to refrigeration unit heat exchanger.

A utility vehicle includes a plurality of ground-engaging members, a frame supported by the ground-engaging members, a powertrain assembly supported by the frame which includes an engine, an alternator coupled to the engine through a housing, and a heating, ventilation, and air condition (“HVAC”) assembly including a compressor operably coupled to the engine. The compressor is supported on a first side of the housing plate and the alternator is supported on a second side of the housing.

Disclosed is an integrated compressor system configured to be integrated with existing air conditioning systems. The integrated compressor system generally includes a mounting assembly, a first compressor and a valve. The mounting assembly can be mounted directly on a condenser of an existing air conditioning system. The first compressor and the valve are mounted directly on the mounting assembly. The valve has a first valve inlet, a second valve inlet and a valve outlet. When assembly and integrated with an existing AC system, the first valve inlet is fluidly coupled to a compressor outlet of the first compressor, the second valve inlet is fluidly coupled to a compressor outlet of the compressor of existing AC system, and a valve outlet is fluidly connected to a condenser inlet of the condenser.
